Luminous 12.2.11 is still default using bluefs_buffered_io = false, which will \
disable the kernel side cache for rocksdb.  It's possible that your NVMe is saturated \
with the massive rocksdb workload when bluefs_buffered_io is disabled. So one way you \
could try is to set the bluefs_buffered_io = true on those OSDs that hold the large \
OMAP object. _______________________________________________
